What marks the arrival of spring?

What marks the arrival of spring? In real life, spring is the first season of the four seasons, and it is also the season when everything recovers. There is a certain sign before spring comes. Introduce you to what marks the arrival of spring.

What marks the arrival of spring? 1 1, everything germinates.

After entering the spring, due to the increase of temperature and humidity, most seeds began to germinate, broke through the seed coat, drilled out of the soil, developed into stems and leaves, and gradually developed into complete seedlings with the passage of time. The germination of willows and green leaves is a sign of entering spring.

2. Flowers and birds

In spring, the temperature rises and the days get longer. Swallows, magpies and other migratory birds have returned to the north one after another, and returned to their breeding grounds from winter. Narcissus, primrose, magnolia, iris, calla lily, begonia, corn poppy, morning glory, peach blossom and so on have been opened one after another.

3. The scene of planting crops

After beginning of spring, spring ploughing is about to begin. In some areas of China, the custom of spring ploughing has been handed down. In northern Guangxi, during the spring ploughing season, urban activities are even more enthusiastic and grand than those in rural areas.

In Yaoshan, the heads of households have to dig several hoes in the fields with hoes on their backs, or dig several hoes in rice fields and vegetable gardens, which means that in addition to digging in spring, they have to go up the mountain to cut some bamboo and insert it in the fields, which means inserting it in the fields and burying a few seeds in the fields, which means a bumper harvest.

Hun yuan, Shuoxian and Yin Shan counties in Shanxi Province and parts of Hebei and Inner Mongolia. There is a popular custom of beating drums to welcome the spring.

Before spring ploughing, people held sheepskin round fans and tambourines, knocking and singing, praying for disaster relief and a bumper harvest after autumn.

In addition to the above scenery, changes in geographical conditions such as temperature and rain are also symbols of spring.

After entering the spring, the temperature gradually rises all over the country. In late March, the average temperature in northern South China is mostly 13℃ to 15℃, and in southern South China it is mostly 15℃ to 16℃. Most of the plateau has been melted by snow, and the ten-day average temperature is about 5℃ to 10℃. Most areas in South China, such as river valleys, have the highest temperature, with an average of 18℃ to 20℃.

In spring, it began to rain and gradually increased. The rainy solar term means that when the rain begins, the temperature can generally rise above 0℃ after the rain. During this period, the average temperature in most parts of southern China was above 10℃, and it has indeed entered the climate spring. In addition to a few years, the frost period has come to an end.

After a dry winter, there are many droughts in spring all year round in South China, especially in the western part of South China, where "spring rain is as expensive as oil". Entering the shock period, the rain is getting bigger and bigger, and the spring thunder suddenly moves. By the time of the earthquake, most parts of China had entered the busy season of spring ploughing. The gradual increase of temperature can also promote the irrigation of everything.

What marks the arrival of spring? 2 1. Jasminum nudiflorum: It was named after it first bloomed in a hundred flowers, and then it ushered in the spring of a hundred flowers. Like light, slightly tolerant of shade, slightly cold, afraid of waterlogging, can overwinter in North China and Yanling in the open air, requiring warm and humid climate, loose and fertile sandy soil with good drainage, which grows vigorously in acidic soil and poorly in alkaline soil. The roots germinate vigorously. The landing part of the branch takes root easily.

2. Primula: it grows mostly in wilderness, fields, wet and empty fields, ditches and forest margins. This species is widely cultivated all over the world, and there are many horticultural varieties. Primula blooms in early spring with rich colors and long flowering period, which has high ornamental value.

3. Daphne: Daphne likes astigmatism, avoiding the scorching sun and being cool in summer. I prefer loose, fertile and well-drained acid soil (pH 6-6.5) to alkaline soil. I can use mountain mud or pastoral soil to mix 40% peat soil, humus soil, pine needle soil and appropriate amount of coal cake ash, rice husk ash, urban garbage and so on. As culture soil.

4. Magnolia: Magnolia has a wide temperature range and can grow above -20~40℃. China is distributed from Xishuangbanna in Yunnan to Heilongjiang in the north. The optimum temperature zone of Magnolia grandiflora is from warm temperate zone to subtropical zone, and the annual precipitation is 500 ~1850 mm. Extreme temperature also affects the growth of magnolia trees, especially seedlings. Roots, buds or branches are vulnerable to freezing in winter, soil freezing and cold cracking wind. Exposure to high temperature and sunlight is easy to burn leaves, and long-term exposure to high temperature and strong light is easy to burn magnolia trunk and form ulcers. Under the scorching sun, the growth of seedlings has been stagnant for a long time. The inadaptability of Magnolia grandiflora to temperature is mainly manifested in its seedlings. The seedlings that grow vigorously in autumn and are not completely lignified are prone to freezing injury, resulting in the death of the above-ground parts.

Iris is produced in Shanxi, Anhui, Jiangsu, Zhejiang, Fujian, Hubei, Hunan, Jiangxi, Guangxi, Shaanxi, Gansu, Qinghai, Sichuan, Guizhou, Yunnan, Tibet, Myanmar and Japan in China. It grows on the edge of shrubs, sunny slopes, forest edges and waterside wetlands at an altitude of 800- 1800 meters, and has been cultivated in gardens for a long time.
